如何将光标焦点设置在wpf usercontrol的文本框中。 [英] How to set cursor focus on wpf usercontrol's textbox.

问题描述

我非常迫切需要解决以下问题。如果您知道请告诉我。



我有WPF网页浏览器项目。在Page1.xaml我有wpf usercontrol usrcntl1。这个usrcntl1有三个文本框txtBox1，txtBox2，txtBox3。



根据业务逻辑，一旦用户在用户控件的文本框中输入值（在Page1.xaml上），我将验证txtBox1，txtBox2，txtBox3值。如果输入了任何错误的值，我将要关注txtBox1。



我无法将注意力设置在usercontrol的文本框中。如果您有任何解决方案，请告诉我。

更新patquotdet设置qdindtslno = 1其中qdpnarefno ='800016692'

和qdpnaslno = 3

谢谢

推荐答案

没有光标焦点这样的东西。所有焦点活动都是关于键盘焦点，没有别的。



WPF有一个专门的系统，你应该学习的焦点： http://msdn.microsoft.com/en-us/library/aa969768.aspx [ ^ ]。



然而，在许多情况下，最简单的方法是：调用 Control.Focus ，特别是 TextBox.Focus 。请参阅：

http://msdn.microsoft。 com / en-us / library / system.windows.controls.control.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.windows.uielement.focus.aspx [ ^ ]。

There is no such thing as "cursor focus". All focus activity is about the keyboard focus, nothing else.

WPF has a dedicated system pertaining to focus you should learn: http://msdn.microsoft.com/en-us/library/aa969768.aspx[^].

Nevertheless, in many case, the simplest thing works: call Control.Focus, in particular, TextBox.Focus. See:
http://msdn.microsoft.com/en-us/library/system.windows.controls.control.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement.focus.aspx[^].
